Abstract

The machine of the present invention is used to produce articles of apparel having an openable front or rear panel. It includes feeder mechanisms to supply two half width webs and webs for reinforced edges through cutter mechanisms where webs cut into segments for the desired garment are overlapped to provide a central opening. Segments are transferred to a carrier drum having folding devices which are operative while the drum rotates. A full width web with a pattern of adhesive pre-applied to selected margins is overlaid on top. The underlying segments have extension flaps along selected margins which are folded around and over the edges of the top panel segment and bondably seamed to it by means on, or co-acting with, the carrier drum. Seams can be made along transverse, longitudinal, or skewed lines by different folding device arrangements. In another embodiment, an openable front or rear panel can be produced by including a transverse vacuum folding roll to half fold overlapped segments into a front/rear panel configuration and means to then fold extensions on each rear half panel over the transversely folded front half portions positioned away from the drum surface. Machine arrangements can include special devices for features like pockets, shoulder pieces, shirt collars, etc.

Claims19

Dependent claims

Apparatus for assembling shaped segments cut from web material to form garments with at least one openable panel including:

means to advance a first half width web and a narrower second web,
means to print adhesive on both sides along one edge of said first web,
means to V-fold said second web,
means to bondably enclose said one edge of said first web within said V-folded second web to form a first web assembly,
means to advance and die cut said first web assembly into a first segment having marginal extensions,
means to advance and transfer said first segment to the bearing surface of a carrier drum moving in a path having a beginning and an end,
means to advance a third half width web and a narrower fourth web,
means to print adhesive on both sides along one edge of said third web,
means to V-fold said fourth web,
means to bondably enclose said one edge of said third web within said V-folded fourth web to form a second web assembly,
means to advance and die cut said second web assembly into a second segment having marginal extensions,
means to advance and transfer said second segment to the bearing surface of said carrier drum in partially overlapped superposed relationship to said first segment,
means to advance a fifth full width web, die cut a third segment therefrom, and transfer said third segment to said carrier in superposed relationship with said first and second overlapped segments,
assembly means on said carrier drum to;
apply a selected pattern of adhesive to marginal areas of said third segment,
apply first positive and second positive force means to fold said marginal extensions of said first and second segments around and over the edges of said third segment,
means to remove the assembled first, second, and third segments from said carrier drum as said drum approaches the end of said path.

14 more elements

A method of fabricating articles of apparel having an openable and re-closeable front or rear panel including the steps of:

unwinding and advancing a first web having a width a few inches greater than one half of the product width and offsetting said first web from the machine centerline,
printing adhesive on both sides along a marginal edge of said first web,
unwinding and advancing a second narrower web in a direction perpendicular to the machine direction path,
V-folding then inversely V-folding said second narrower web while concurrently orienting said second narrower web in the machine direction path,
advancing said first web in the same direction as, and for enclosure by, said second web to form a first, web assembly,
unwinding and advancing a third web having a width a few inches greater than one half of the product width, and offsetting said third web from the machine centerline in a direction opposite from said first web offset,
printing adhesive on both sides of said third web along marginal edges,
unwinding and advancing a fourth narrower web in a direction perpendicular to the machine direction path,
V-folding then inversely V-folding said fourth narrower web while concurrently orienting said fourth web in the machine direction path,
advancing said third web in the same direction as, and for enclosure by, said fourth web, to form a second web assembly,
advancing said first web assembly through a die roll cutter and transferring said first segment to the vacuumized surface of said carrier,
advancing said second web assembly through a die roll cutter and transferring a second segment in overlapped superposed relationship to said first segment,
unwinding and advancing a fifth web through a die roll cutter to form a full width third segment,
transferring the full width third segment in superposed relationship with said overlapped first and second segments on said carrier,
printing an adhesive pattern along the margins of said third segment,
folding extended portions of said first and second segments of a front panel over said third segment of a rear panel to form a conjoined assembly,
advancing the conjoined assembly along said machine direction path,
applying closure means between said front panel segments,
removing said conjoined assembly from said machine direction path.
